TIRE CHAIN AND GUARD.

To all whom it may concern;

Be it known that I, OLE J. MIKKELSON, a citizen of the United States, residing at F erryville, in the county of Crawford and State of Wisconsimhave invented certain 7 new and useful Improvements in Tire Chains and Guards, of-which the following is a specification.

My invention relates to improvements in tire chains or'guards and refers particularly to such a pliances as are used upon tires to prevent sipping or what is known as skidding.

The object of my invention is the provision of means which can be readily placed upon the tire and which are capable of adjustment'totires of various sizes and which will be of the proper flexibility but which will have a biting action upon the road or surface to prevent slipping of the tire.

Another object of my invention is the provision of a device of this character which can be readily applied and detached and which will not interfere with the easy riding of the tire and which will be of extremely simple and inexpensive construction to insure an efficient and practical improvement of this character.

With these objects in view, my invention consists of the tire chain or guard embodying novel features of construction and'combination of parts substantially as disclosed herein.

Figure 1 represents a side elevation of a sufficient portion of a tire with my chain or guard applied thereto. Fig. 2 represents a perspective view of one of the sections or members of the device to show its peculiar construction, and Fig. 3 represents a per spective view of the novel form of adjustable connection for the free ends of the chain or guard.

In the drawings: The letter A designates a portion of the tire to which myschain or guard is applied and the said chain or guard comprises the series of curved members B,

which are of a shape to snugly fit upon the tire and are tapered in form and provided with the flanged edges 0, and by means of the tapering form and the arrangement of the flanges when the tire passes over the surface the efiect is to cause the first flange to engage the surface and force the second or rear flange into the surface which is a very important feature and constitutes a point of merit of my device,as this construction Specification of Letters Patent.

slide over the surface and not prevent slipping.

The series of members. are connected by the links I) and to connect the ends of the chain and to secure the chain upon the tire, I use the novel device shown in Fig. 3, which consists of the loop E, which engages the rim and has its ends riveted at F to the pair of links G, which links at one end are provided with hooks H, engaging pins J on the end member K, and to the other end of said links are fulcrumed at L, the pair of levers M, which are formed with openings N to engage the pins 0 on the other or meet ing end member P. These levers are secured in place by means of the fastening Q, secured to the end of the levers and passing around the rim.

In use, the device is applied to the tire and the series of members fit snugly in lace and are secured upon the tire by the ad iush ing devices and it is evident that in passing over the ground the chain will give sufliciently but the plates or members byreason of their peculiar form, Will bite into the surface and prevent slipping;

It is also apparent that my device can be quickly applied or removed and easily adends of the chain and securing the chain upon the tire, said means consisting of a pair 0 links having hooks at one end to engage one set of end members, a loop connected to said links to engage the tire rim, and a pair of levers fulcrumed to the other end of said links and having open recesses to engage pins on the other member of the chain at the meeting end.

2. In combination with the end members of a chain or guard provided each with lateral pins, a engage the pins on one member, a pair of its pair of links having hooks to levers fulcrumed to the other ends of the In testimony whereof I affix my signature links and having recesses to engage the pins in presence of two witnesses. on the other member, and. means pivotally carried upon the rear ends of the hook can OLE MIKKELSON' 5 1' ing links and passing around the rim of Witnesses:
